A. A. WASHBURN, OF ST. JOHNSVILLE, NEW YORK.

WASHING-MACHINE.

Specification of Letters Patent No. 27,249, dated February 21, 1860.

To all whom 'it may concern:

Be it known that I, A. A. VVASHBURN, of St. Johnsville, in the county ofMontgomery and State ofNew York, have invented a new and ImprovedWashing-Machine; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, forming a part of this specification, in which-Figure 1 represents a longitudinal vertical section of this invention.Fig. 2 is a plan or top view of ditto.

Similar letters in both figures refer to corresponding parts.

This invention relates to certain improvements in that class of washingmachines in which a concave swinging tub, and a stationary washboard,together with two pounders, is employed; and the invention consists inarranging in the wash-board two liuted rollers, to operate incombination with the corrugated bottom of the tub and with pounders cutout so as to correspond. to the rollers for the purpose of facilitatingthe rubbing and squeezing of the clothes without injury to the same, andthis invention consists also in combining with the swinging tub acounterpoise, whereby the exertion necessary to keep the tub in motionis considerably reduced.

To enable those skilled in the art to make and use my invention I willproceed to describe it.

A represents a concave tub suspended from a pin, b, that rests on twostandards c,

and said tub is provided with two handles, B, which serve to impart tothe same a swinging motion. The bottom, C, of the tub is corrugated, andsecured in its center is the wash-board, D, which consists of twoupright slats, el, which are secured to the standards, o, by means ofthe pin, b, and another pin, b', which latter passes through the top ofthe standards and of the slats, as clearly shown in Fig. 2. The slatsare connected at the lower end by means of a cross brace, f, and byanother brace, g, at a small distance below the pin, b. Between the twobraces are the corrugated rollers, E, arranged so as to rotate freely ontheir pivots, h. The pounders, F, are firmly secured to the bottom ofthe tub at equal distances from its center, and the inner surfaces ofsaid pounders form concaves, z', to correspond to the corrugatedrollers. On the top of theI tub, and secured to the same by asemi-circular arc, G, is a counterpoise, H, the momentum of whichassists materially in operating the tub.

The tub is filled with water and soapsuds, as indicated in Fig. 1, andthe clothes are placed into the water and between the pounders and therollers and by imparting to the tub a swinging motion the washing iselfected. i

What I claim as new, and desire to secure by Letters Patent, is

The arrangement of the fluted rollers, E, and the stationary wash-board,D, in combination with the corrugated bottom of the tub and with theconcaves, z', in the pounders, F, substantially as and for the purposespecified.
